Can’t plan event at restaurant

You can throw other types of parties (including original BG weddings) at restaurants, so I think it's just an oversight.

Normally they just pick tables as close to the original one as possible if there is overflow. Setting up a separate function room for parties is usually a good plan.

I see. Yeah, that makes sense

Purely speculation on my part, but I’m guessing it’s because it could be problematic for the AI.

You’d have all the normal restaurant customers trying to run on the regular script for seating, ordering, and eating food in conjunction with the regular AI script for guests of wedding-related parties.

And then there’s the wait staff, who weren’t originally programmed to seat and wait on (literal) parties that large.

Not to mention the group settings, where typically going to a restaurant requires all attending sims (NPC or not) to be in a single group in order to be seated at the same time.

I’m not sure that there’s a clean/effective way to do both restaurant gameplay and wedding events simultaneously without causing bugs.
